1 MEAT CUTTER.

To all whom t may concern:

Be it known that I, GENrAH B. .RnNYAm a citizen of the United States, anda resident of Kusa, in the county of Okmulgee and State of Oklahoma, have invented `certain new and useful Improvements in Meat Cut*- ters, of which the following is a specht cation.

My invention relates to improvementsir` meat cutters and it consists of the constructions, combinations and arrangements here in described and claimed.

ein object of the invention is to provide a meat cutting apparatus which is mounted on y an overhead support and which is so arranged that it may be pulled into a cutting position and when released .will move back into the` original position.

A. further .object oit the invention is to provide ameatcutting apparatus which is KJ mounted on an overhead `cable or wire upon which it .is adapted to travel back and i'orth int-o ine operative and out-of-the-way positions. i.

A further object of the invention is to provide a meat cutting apparatus consisting of a framework which carries all of the essential elements, this framework being mounted to run on an overhead cable yor wire. V

further object of the invention is to provide a meat cutting apparatus in which the bone saw is separate from the meat `cutting blade, the clutch by which lthe saw is operated being entirely independent of the handle which slides the saw back and forth, thereby permitting` sliding the sawwhether n it is in revolution or not.

Other objects and yadvantages will appear in the following specilicatiom-referencebeing had to the accompanying drawings, in which: s

The meat cutter herein disclosed is improvement yon the meatV vcutter disclosed in m allowed applicationy Serial No.. 580,- 814, liled Aug. A9, 1922. ,The meat 'clutter in this application is portable, Lthat `is`ftosay, it consists of a small vframe whichcarijies the cutting blade and bone saw, there beingy a flexible shaft between the shaft which ,carlries these blades `andan operatingfelectric motor. The kapparatus v`,in the present `application is `an improvement over ythe old con-` struction. The operating motor,the two. blades, and `other parts of `the ;mechanism, aremounted on a framewhich, itself, is carried `by van overhead wire. All thatthe operator has'to do is to pull-fthe frame toward' him lwhen it is desired to out meat or a bone, none of the weightof the apparatus being imposed uponhim as inthe caseof thefportable cutter.y

The construction y comprises, a trame which is generally designated, 1.`v Thisframe .consists of upper and lower-sections 2 and 3 respectively, which vare of.. .corresponding diverginglshapes, (Fg.- 1)Ythe upper one of which carries a pairlof standards 4; which are suitably shaped atthe upper ends to carry `the grooved pulleys 5 by means of which the frame is mountedto run on the overheadwire 6. No means of fastening the ends of this wire are lshown but the useof hooks, eye bolts, suspended rodsetc., seems` so obviousthat illustration is unnecessary. The .Wire 6; should. be stretched rtightly .and must `also be of suiiicient .tensile strength that itwill not sag unduly under. the weight of the meat cutter.

the operatoreither lifts up or. presses vdown on the lower'fsec-tion. The weight of the lower section is counterbalanced, by ,a block 9B .Pendent fromthe upper section 2 are three `tubes 7. ,t These are lixedbeneaththe of metal or other suitable material 12, suspended by a cord 13 which runs over a grooved pulley 14 on a rod 15 on the upper Section 2. The other end of the cord 13 is suitably attached to the section 3, for example, by means of a bent rod 16. The purpose of the counterweight 12 is precisely like that of the counterweight in the ordinary window frame. It enables lifting the section 3 up and down so as to either remove the cutting blades or introduce them to the meat.

A number of braces rigidify the various parts of the frame 1. For example, the upper section 2 is reinforced by a plate 17, the front tubes 7 are strengthened by crossed rods 18 and the front of the lower section 3 is strengthened by a curved bar 19. "This bar is useful in supporting one end of a slide rod 20 upon which a collar 21 is adapted to slide back and forth. Thisv collar has a pendent rod 22 which terminates in aL plate 23 'by means of which connection is made with a clutch sleeve 24. The rod carries a handle 25 so that it may be conveniently grasped by the operator and moved back and forth. The plate 23 is secured to the sleeve 24 by means of a screw 26. rlhe sleeve has a rather heavy closed end 27 into which the screws 26 are threaded and which provides a base of ample proportions for sliding on the motor shaft 28. y

A screw 29 at the front of the sleeve 24 is adapted to occupy the groove 30 inthe saw hub 31 and thus providea swivel mounting for the saw blade 32. This blade is circular asshown, The motor shaft 28 may revolve independently of the hub 31 without affecting the saw. It is only whenthe clutch 33 is moved toward the hub y31, that the blade' rollers 42 which are located in a circular groove 43 'in the clutch. y Theposition Lof the sleeve 24 is fixed, so far as rotation yis concerned, by its attachment to the plate 23 of the rod 22. Therefore, the handle 38'isy also Xed. A movement of the handle 38 in opposite directions will either connect the saw 32 with the shaft 28 or disconnectit therefrom. y

A motor 44 drives the shaft 28. yIny fact, the shaft `28 is the motor shaft. The motor is supported pendently from the'section 3 by means of brackets 45. The front end of the motor shaft 28 is supported in a bearing 46 (Fig. 4) lwhich may be described as part of the section 3 inasmuch as it is carried by Vthe brackets 47 which extend down beneath and that less power at the motor 44 will be required to turn the knife blade.

Fastened to the front of they upper sectiony 2 is a cord 52 which runs over a pulley 53 and has a handle 54 within convenient reach of the operator. The purpose of the handle and cord vis to permit pulling the frame 1 forwardly so as to bring the blade 48 into position to cut the meat M on the block B. rlhe pulling of the cord 42 is done against the tension of a spring 55 which is intended to hold the frame back in a predetermined normal position away from the block B.

One end of the spring 55 is attached to the frame 1 while the other end is attached to a clamp 5G on the wire 6. clamp 57 supports the pulley 53. clamps may be moved if desired.

These For eX- ample, the user of the meat cutter may de-` sire to station the apparatus in a different predetermined normal position in respect to the meat block and in such event he will doubtless find it necessary to unloosen the clamps 56 and 57 and move them to a different position along the wire' 6.

rlhe operation may be readily understood after a brief review. lt has already been stated that the frame l is intended to occupy a predetermined normal position on the wire 6 and in respect to the meat block B. The lower section 3 may be raised up and down so as to either get the blades 48 and 32 out of the way or bring them into such positions that they will register with the meat M. The weight12 is a counterweight which is adapted to support the section 3 and its carried parts in any adjusted position.

Assume that the operator has pulled the` section 3 down such a distance that the edge of the circular knife 48 will touch the upper surface of the meat M. 'He will bear down on the section 3 so as to accomplish the cut. As soon as the bone is reached, the saw 32 must be brought forwardly. This is done by grasping the handle 25 and sliding both and collar 2l and sleeve 24 along the rod 2O and shaft 28 respectively. The saw 32 remains stationary up to the time that the handle 38 is thrown backward. This will move the clutch 33 into engagement with the saw hub 31 so that the rotating shaft 28 will' have connection with the Saw andA cause the latter to rotate.

rlhe saw 32 may be slid back and forth Similarly a CII ltll) llO along the motor shaft 28 regardless of whether the clutch ,33 is in or out. The shaft 28 is capable of rotating independently' of the saw. The hub part 27 of the sleeve 24 furnishes a bearing which guards against any possiblewsagging of the shaft 28m the middle.

As soon as the bone is sawn through, the clutch 33 may again be disengaged, the handle 25 slid back and the blade 48 pressed down until the entire slice is cut off'. It is necessary that the knife blade 4S be capable of swinging transversely of the meat M. The frame l is capable of rocking in respect to the wire 6, the gro'oved pulleys 5 functioning as hinges for this purpose. The handle 54 is for the purpose of pulling the entire frame forwardly as far as may be necessary for the blades 48 and 32 to reach the meat. Upon release of the handle .54 the spring 55 drawsthe frame and its carried parts back to a predetermnied normal position. This position may be varied by undoing the clamps 56 and 57 and moving them to new positions along the wire 6.

Vhile the construction and arrangement of the improved meat cutter as herein described and claimed, is that of a generally preferred form, obviously modifications and changes may be made without departing from the spirit of the invention or the scope of the claims.
